plan

A workflow for turning a software task into a written implementation plan based on the current codebase. It records the relevant code locations, specifications, dependencies, and steps.

In plain words
What is it for?
Use it to plan a new feature, bug fix, or backlog task before coding. It files the plan in the project's active plans area.
Why use it?
It prevents plans based on guesswork or outdated code. Future work can start from verified context instead of repeating the investigation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

plan scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Plan a piece of work

A plan is a promise a future session can execute without re-deriving context. Discovery happens in the codebase before a word is written; every anchor is verified, every touched spec is named.

Steps

  1. Consult. Read data/product.md — especially ## Constraints and ## Authoring rules, which bind what you write. Check for related work: iwe find --fuzzy <topic> -f keys, the relevant data/spec/ and data/features/ docs, and whether an active plan already covers this (iwe find --included-by data/plans -f keys).

  2. Discover. Read the code the plan will touch. Collect the entry points, the functions to modify, and their current line numbers — these become ## Key references, and they must come from the current checkout, not memory.

  3. Create. iwe new --key data/plans/<YYYYMMDD>-<slug> (today's date, kebab slug), then write:

    ---
    created: <today>
    ---
    

    Body sections, in order (omit a section only when it's genuinely empty):

    • ## Context — why now, linking the feature/bug/backlog doc that motivates it
    • ## Approach — the shape of the solution and the alternative you rejected, in a few sentences
    • ## Implementation Steps### Task N: <name> blocks, each with **Files:** Create:/Modify: ... and - [ ] checkboxes
    • ## Spec changes — every data/spec/ doc this work will create or change; name not-yet-existing specs in back-ticks (never dangling links)
    • ## Depends on — inline links to plans that must ship first (omit if none)
    • ## Verification — how a session proves the work is done: commands, tests, manual checks
    • ## Out of scope — what this plan deliberately does not do
    • ## Key referencespath:line — symbol list under a line Verified anchor points (line numbers as of <today>):
  4. File it. Add an inclusion link under ## Active in data/plans.md. If the plan implements a proposed feature, set the feature doc to stage: accepted. If it grew from a backlog task, mark the task done and move its link.

  5. Validate. iwe normalize, then iwe schema validate — must pass.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

plan is a skill published in the GitHub repository iwe-org/dev-workspace (5 stars, last pushed 23d ago), licensed MIT. It adds 68 tokens to every session and 743 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
